Abstract
At noise component addition section, a noise equivalent value equivalent in size to noise component is calculated using a constant which is dependent on a difference of spreading factors between a common pilot channel and packet channels, and at correlation matrix and correlation vector calculation section, the noise equivalent value is added to diagonal elements of an autocorrelation matrix. At weight calculation section, an optimal weight is calculated using the autocorrelation matrix whose diagonal elements have been added the noise equivalent value, and at adaptive equalization section, equalization of reception signal is carried out. Thereby, noise enhancement produced in the packet channels after the equalization due to the difference between the spreading factor of the common pilot channel and the spreading factor of the packet channels can be reduced.
